Radio-controlled Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.

•This watch is designed to pick up the time calibration signal transmitted in Germany (Mainflingen) and England (Rugby).

Current Time Setting

This watch adjusts its time setting automatically in accordance with a time calibration signal. You can also perform a manual procedure to set the time and date, when necessary.

•The first thing you should do after purchasing this watch is to specify your Home Time Zone, which is the time zone where you will normally use the watch. For more information, see “To specify your Home Time Zone” below.

•When using the watch outside the range of the Germany and England time signal transmitters, you have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.

To specify your Home Time Zone

1. In the Timekeeping Mode, hold down Afor about five seconds until the second hand moves to the currently selected GMT differential value and stops. This is the setting mode.

• The GMT differential value indicates the time

difference in hours between Greenwich Mean Time and the currently selected time zone.

2.Press Bto select the time zone you want to use as your Home Time Zone.

GMT+ 0 (12 o’clock): London

GMT+ 1 (1 o’clock): Paris, Berlin, Milan, Rome, Amsterdam, Hamburg, Frankfurt, Vienna, Barcelona, Madrid

GMT+2 (2 o’clock): Athens

3.Press Aeight times to exit the setting mode.

•The watch will also return to the Timekeeping Mode if you do not perform any operation for about two or three minutes.

•Normally, your watch should show the correct time as soon as you specify your Home Time Zone. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night). You can also perform manual receive or you can set the time manually.

•Even if the time calibration signal is received correctly, there are some times when the analog hands may not indicate the correct time. If this happens, use the procedures under “Adjusting the Home Positions” to check the home positions of the hands, and make adjustments as required.

•The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between time zones (GMT differential values) and transmitters, see “Transmitters”.

•See the maps under “Reception Ranges” for information about the reception ranges of the watch.

•The actual level at which some functions are disabled depends on the watch model.

•Be sure to read “Power Supply” for important information you need to know when exposing the watch to bright light.

If the analog hands aren’t moving...

If the analog hands aren’t moving, it means that the power saving mode has stopped them to save battery power.

•See “Power Saving” for more information.

•The hands also stop whenever the battery level reaches Level 3.

Time Calibration Signal Reception

There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.

• Auto Receive

With auto receive, the watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive”.

• Manual Receive

Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see “To perform manual receive”.

Important!

•When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 9 o’clock side facing towards a window. Make sure there are no metal objects nearby.

•Under good reception conditions, signal reception is possible within a radius of about 1,500 kilometers from a transmitter.

•At distances further than about 500 kilometers from a transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.

•See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.

About Auto Receive

The watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on your currently selected Home Time Zone, and whether standard time or Daylight Saving Time is selected for your Home Time Zone.

Note

•The auto receive operation is performed only if the watch is in the Timekeeping Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while you are configuring settings.

•Auto receipt of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily.

•The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.

•Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time is actually the correct time.

To perform manual receive

1. Place the watch on a stable surface so its 9 o’clock side

is facing towards a window.

2. In any mode, hold down Bfor about two seconds until

the watch beeps.

3. When you release B, the second hand will move to

READY to indicate that the watch is setting up for time

calibration reception.

• The second hand will move to WORK and stay there while actual reception is in progress.

• The hour and minute hands continue to keep time normally.

• Time calibration signal reception takes from two to

seven minutes, but in some cases it can take up to 14 minutes. Take care that you do not perform any button

operations or move the watch during this time.

• If reception is successful, the second hand will move to YES. One or two minutes later, the hands will move to the correct time.

Note

•To interrupt a receive operation and return to the Timekeeping Mode, press any button.

•If reception is not successful, the second hand will move to NO. One or two minutes later, the second hand will resume normal operation, without any adjustment of the hand setting.

•If the second hand is pointing to YES or NO, you can return to the Timekeeping Mode by pressing any button.

Viewing the Latest Signal Reception Results

You can use the Receive Result Mode to check if signal reception was performed correctly.

To check the latest signal reception results

Enter the Receive Result Mode.

• If the watch was able to perform a successful signal

receive operation since midnight, the second hand will move to YES. If the watch has been unable to receive

any signal successfully, the second hand will move to

NO.

• To return to the Timekeeping Mode, press Bthree times.

• The current receive result is cleared when the first auto receive operation is performed on the following day. This means YES indicates successful signal reception since the start of the current day.

•YES continues to be indicated even if an attempt at manual receive fails after auto receive is successful.

•If you adjust the time or date setting manually, the second hand will move to NO.

• If the home position of the second hand is currently correct, it will move to the 12 o’clock position.

2. While in the Home Position Adjustment Mode, hold

down Afor about five seconds. This will cause the

second hand to make one revolution and stop at its

current home position.

• The analog hands do not keep time during home position adjustment.

3. Check the position of the second hand.

• The second hand home position is correct if it is pointing at 12 o’clock.

• If the second hand is not pointing at 12 o’clock, it means that its home position is off. If this happens, press B to move the second hand clockwise in onesecond steps, until it points at 12 o’clock.

4. Press A to advance to hour and minute hand home position adjustment.

• If current hour and minute hand alignment is correct,

they will both move to 12 o’clock.

5. Check the position of the hour and minute hands.
